无法在Microsoft Azure上运行Dash应用程序

Question

我用Python构建了一个小型Dash应用程序，并成功地将其部署在Heroku上。链接在这里：https://covid19-datachallenge-uconn.herokuapp.com/

但是，我尝试在Microsoft Azure上执行相同操作，但出现以下错误。我正在使用此链接进行部署：https://www.phillipsj.net/posts/deploying-dash-to-azure-app-service/

我可以看到它正在发生，因为它无法导入破折号。该应用程序在我的本地主机和虚拟环境（按博客为Azure部署创建的）上运行良好

请帮助！

在Azure Web应用程序的``配置''设置中，以 gunicorn application：app.server -b：8000

的形式提供启动命令
